The question between us is what does that leadership role mean.You are correct, but I think the Catholic position on your second point would be that the power to bind and loose is the power to legislate. All of the Apostles were given the authority to forgive sins:
*"19 On the evening of that first day of the week, when the disciples were together, with the doors locked for fear of the Jewish leaders, Jesus came and stood among them and said, “Peace be with you!” 20 After he said this, he showed them his hands and side. The disciples were overjoyed when they saw the Lord.
21 Again Jesus said, “Peace be with you! As the Father has sent me, I am sending you.” 22 And with that he breathed on them and said, “Receive the Holy Spirit. 23 If you forgive anyone’s sins, their sins are forgiven; if you do not forgive them, they are not forgiven.”* (John 20:19-23)
Peter’s status as leader of the early Church, however, is evident from the words Jesus spoke only to him and we see his role as leader clearly played out in the Book of Acts.
